SPECIFICATION forming part of Letters Patent No. 614,687, dated November 22, 1898.

Application filed December 27,1897. Serial No. 663,669. (No model.)

T0 on whom it may concern:

Be it known that I, THOMAS ASHWORTH, a subject of theQueen of Great Britain and Ireland, residing at Urmston, near Manchester, in the county of Lancaster, England, have invented new and useful Improvements in or Relating to Apparatus for Spinning and Doubling Cotton and other Fibrous Substances, of which the following is a specification.

This invention relates to apparatus for the formation of cops of yarn upon bare spindles or upon paper or other tubes fitted thereon; and it consists of improvements on the mechanism for which I have made an application fora patent in the United States of America December 22, 1897, Serial No. 663,045, the objects of the present invention being to improve the bearing for the short tubular flier, to improve the spindle and the footstep for carrying the same, to simplify the doffing of the cops, and to prevent the spindles from being lifted during the operationof doffing.

In the accompanying drawings, Figure l is a vertical section of the spindle and flier with their improved bearings and footstep, and Figs. 2, 3, and 4 are detached views of details hereinafter more particularly referred to.

In Fig. 1, c is the spindle-rail, and b the lifting-rail; o, the spindle; d, the short tubular flier, with cup-shaped enlargement d at the top and Wharve CZXX. To improve the bearing of the short tubular flier, I fix in v place of the long collar (which according to my original invention formed the upper part of the bolster) a tube 1", of steel or hard brass, and from about the center upward I reduce the diameter so as to make a shoulder thereon at s, and upon this I place (being pinned, as at t, or otherwise arranged so as not to revolve thereon) a tubular shell 2, and I bore out the inside of this shell in a corresponding manner, so that the inner shoulder of the shell 6 shall rest upon the shoulder s of the fixed stud or brass collar r. I bore out the lower part of the tubular shell i a little larger, so that it is a loose fit round the lower part of the fixed collar r. I slightly cone the upper part TX of the latter, so that the tubular shell 15 can oscillate in a very slight degree to accommodate itself to any vibration caused by the unevenness of pull, but will always immediately return automatically to its true vertical position.

I prefer to make the foot of the spindle in the form shown in Fig. 1, and the footstep u is made a loose fit in its hole in the rail b, but is prevented from turning around therein by a pin a or equivalent device, Fig. 4:. It is provided with a flange u above the rail, which rests upon the latter, and the under side of this flange is cut or beveled away at the back, so that the action of gravitation will cause the footstep u to have a constant tendency to fall forward at the bottom, as shown. This manner of consi ructing and arranging the footstep gives the same freedom of action to the spindle c as is aiforded to the tubular flier d, but allows the spindle always to gravitate automatically into its true vertical position, and by thus constructing the bearings of the spindle and flier I am enabled to drive the frame at very high velocities with no perceptible vibration.

Pins or screws 15 serve as pivots upon which to hang a light wire brake-frame k, on which is stretched a suitable band of canvas or web bing or a tuft of cotton or other suitable material Z, which bears against the spindle passing through the bolster h, a small quantity of oil or other lubricant being preferably applied to this material on the frame.

WVhen spinning upon the bare spindle c, the upper end of the said spindle (see Fig. 1) is bored down for a short distance, and the extremity of the tube so formed (which is very thin) is notched or vandyked at the top, so as to leave a point (or two points) gradually widening to about half the circumference of the tube, into which I then drive or fix tightly a peg 0 the end of which extends from the tube for a short distance and forms the point of the spindle. Instead of forming this tubular part out of the spindle itself I may make it a separate piece by reducing the outside diameter of the spindle at the point, as shown at Fig. 2, and fixing thereon a short shell 0, on which I form the vandykes at the upper edge.

To attach the yarn to the spindle, the end is turned once or twicearound the spindle and drawn down between one of the points of the tube, at the end thereof, and the peg 0 Fig. 1, or the filling-top of the spindle, Fig. 2, until the yarn end reaches or nearly reaches the root of the point, where it will be held curved around about half the circumference of the spindle and prevented from being drawn out lengthwise. The point of the tube will spring outward sufliciently to allow of the insertion of any ordinary count of yarn, which can also be readily removed by the upward motion in doffing.

lVhen spinning upon thin metal or other tubes, I can apply my invention by making the upper end of each vandyked or with points, as shown in Fig. 3. This, again, will act exactly like the point on the spindle itself, which in this case may be plain, as usual. The doffing of the yarn will be quite easy, as the points will be removed with the cop.

To prevent the spindles c from being lifted from their footsteps a when dofling the cop, I either make the foot of the spindle with a shoulder at c as shown in Fig. 1, or I provide each spindle with a light collar or flange above the footstep, and I mount a light rail upon the lifting-rail b, with an upper flange projecting just above the shoulders or collars on the spindle, and in the front of this flange I cut out a notch opposite to each spindle sufiiciently large to allow the spindles to be removed and replaced when desired. This rail 1) is mounted in such a manner that it can slide a short distance to the right or to the left, and when the cops are finished and it is desired to dolf them it is to be moved by hand, say, to the right, so as to bring one side of the notch over the flange or shoulder of each spindle. Then the lifting-rail I) is wound down by hand in the usual manner, carrying all the spindles with it and leaving all the cops in the cups d of the fliers, and as the cops are being removed each end is broken and inserted in the cleft between the spindle and the vaudyke-point, and the notched rail '0 is moved into its original position, leaving each spindle free to be raised up, if required, and the frame may then be set in motion in the ordinary manner to commence a fresh set of oops.

I claim as my invention- 1. A spindle provided at the top with a tubular part having vandykes or points, and means for filling said tubular part, as and for the purpose described.

2. A spindle bored out and plugged at the top and having vandykes or points, as and for the purpose described.

3. A tubular flier with a cup or trumpet shaped mouth at the top and a long tube fixed in the bolster and provided with a shoulder outside, and carrying a loose shell with a corresponding shoulder inside, in combination with a spindle, revolving in the fixed tube and the shell hanging loosely on the shoulder and supporting the tubular flier, with means whereby the shell can rock slightly on the shoulder, but cannot revolve, as and for the purpose described.

4. The combination of a spindle-rail with a footstep for spindles loosely fitted in the hole in the spindle-rail and provided with means whereby it is prevented from turning, and provided with a flange at the top resting on the rail, the under side of such flange being beveled away gradually toward the back, whereby the said footstep may have a constant tendency to fall forward at the bottom, substantially as hereinbefore described.

In witness whereof I have hereunto set my hand in presence of two witnesses.
